Creating subdirectory domain names
Domain names are composed of at least two levels, a top-level domain and a second-level domain. The top-level domain, also referred to as TLD, is the suffix or extension attached to Internet domain names. There are a limited number of predefined TLDs, such as .com, .net and .org.
A second-level domain (SLD) is the portion of a Uniform Resource Locator (URL) that identifies the specific and unique administrative owner associated with an Internet Protocol address (IP address). The second-level domain name includes the top-level domain name. For example, "NetNation.com" is a second-level domain, as it includes the domain name "NetNation" and the top-level domain "com."
If you need to further distinguish your second-level domain name, you can use a third-level domain name, such as "help.netnation.com."
When a third-level domain name points to subdirectory in your current site, this is referred to as a "subdirectory domain name."
Third-level domains can also be set up as a domain alias to a target domain or as a separate Web hosting account. To set up these types of domain names, you need to edit your DNS/MX record. For details, see Editing DSN/MX records.
To create a subdirectory domain name:
- In AccountManager, click Domain Name > Manage Subdirectory Domains. The Subdirectory Domain Summary page lists any active subdirectory domains that have already been set up for your domain.
- Click Add Subdirectory Domain. When the Add Subdirectory Domain Name page appears, carefully review the restrictions and information about any additional fees that may apply.
- Enter the name of the subdirectory domain you want to create.
- Click Add Subdirectory Domain Name to create the specified subdirectory.
